Childhood Cancer (Pediatric Cancer)

Childhood cancer, or pediatric cancer, is a tough diagnosis for any child or family. It’s a fight that affects not just the child but their whole family. We need to raise awareness about childhood cancer to support these brave kids.

When a child gets cancer, their life changes forever. They lose the simple joys of childhood. It’s vital to know about the different cancers, their signs, and treatments. This knowledge helps us fight cancer in kids.

This article will cover all about childhood cancer. We’ll look at common cancers like leukemia and brain tumors. We’ll also talk about newer treatments and how to support kids with cancer.

By understanding and raising awareness about pediatric cancer, we can help kids fight this disease. With love, support, and top-notch care, kids can beat cancer and live healthy lives. Let’s all support kids with cancer and their families.

What is Childhood Cancer?

Childhood cancer, also known as pediatric cancer, happens in kids and teens under 18. It’s different from adult cancers because it often starts in other parts of the body. Pediatric oncology is the field that deals with treating cancer in young patients.

Even though it’s rare, childhood cancer is a big worry. The National Cancer Institute says about 15,000 kids in the U.S. get cancer every year. Thanks to new treatments, more kids are surviving cancer today.

Defining Pediatric Cancer

The childhood cancer definition covers many types of cancer in kids and teens. These cancers can start in the blood, bones, brain, and other organs. Because they grow fast, kids need quick and special treatments from pediatric oncologists.

Types of Childhood Cancers

There are several main types of childhood cancers:

• Leukemia: Cancer of the blood and bone marrow
• Brain and spinal cord tumors: Tumors in the central nervous system
• Lymphoma: Cancer of the lymphatic system, including Hodgkin’s and non-Hodgkin’s lymphoma
• Neuroblastoma: Cancer that develops from immature nerve cells
• Wilms tumor: Cancer of the kidneys
• Bone cancers: Cancers that originate in the bones, such as osteosarcoma and Ewing sarcoma
• Soft tissue sarcomas: Cancers that develop in muscles, tendons, and other soft tissues
• Retinoblastoma: Cancer of the eye that mainly affects young children

Knowing about these cancers helps doctors find them early and treat them well. The next parts will dive deeper into some of these cancers, talking about their signs, symptoms, and how to treat them.

Childhood Leukemia

Childhood leukemia is the most common cancer in kids, making up about 30% of all cancers in children. It’s a cancer of the blood and bone marrow. Here, abnormal white blood cells grow too much and push out healthy cells. The main types are acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML).

ALL is the most common type, making up about 75% of cases. In ALL, the bone marrow makes too many immature lymphocytes, a type of white blood cell. Kids with ALL might feel tired, look pale, bruise easily, have bone pain, and get sick often. Doctors use blood tests and a bone marrow biopsy to diagnose it.

AML makes up the rest of the cases. It affects myeloid cells, another type of white blood cell. Symptoms are similar to ALL but might include swollen gums and skin rashes. Treatment for both types usually includes chemotherapy, targeted therapy drugs, and sometimes stem cell transplantation.

Thanks to research, survival rates for childhood leukemia have gone up a lot. Kids with ALL now have a 90% chance of surviving 5 years. For AML, it’s about 70%. But, treatment can cause long-term side effects. This shows we need to keep working on better, less harmful treatments for kids.

Childhood Brain Tumors

Childhood brain tumors are a common type of cancer in kids, hitting thousands in the U.S. each year. They grow in the brain or central nervous system. The size, location, and how aggressive they are can vary. Finding and treating them early is key to better outcomes and quality of life for kids.

Symptoms and Diagnosis

Symptoms of childhood brain tumors can be hard to spot and may include:

If a child keeps having these symptoms, a doctor might suggest imaging tests like an MRI or CT scan. These tests help find a tumor. A biopsy might also be needed to know the tumor’s type and grade.

Treatment Options for Pediatric Brain Tumors

Treatment for childhood brain tumors depends on several things. This includes the tumor’s size, location, and type. The child’s age and health also play a role. The main treatments are:

• Surgery: Removing the tumor is often the first step. The goal is to take out as much of the tumor as possible without harming healthy brain tissue.
• Radiation therapy: This uses high-energy beams to kill cancer cells. It might be used after surgery to get rid of any leftover tumor cells or as a main treatment for tumors that can’t be removed.
• Chemotherapy: Anti-cancer drugs are given to kill cancer cells all over the body. Chemotherapy might be used alone or with surgery and radiation therapy.

Children with brain tumors may also get supportive care to manage symptoms and side effects. This includes medicines for pain, nausea, and seizures. Keeping a close eye on them and following up is important to catch any signs of the tumor coming back or long-term effects of treatment.

Thanks to advances in treatment, more kids are surviving brain tumors. But, the journey is tough for kids and their families. Support from healthcare teams, family, and friends is vital. It helps kids deal with the physical and emotional effects of a brain tumor diagnosis and treatment.

Childhood Lymphoma

Lymphoma is a cancer that affects the lymphatic system, which is part of the body’s immune system. It happens when abnormal lymphocytes, a type of white blood cell, grow uncontrollably. There are two main types of childhood lymphoma: Hodgkin’s lymphoma and non-Hodgkin’s lymphoma.

Hodgkin’s Lymphoma in Children

Hodgkin’s lymphoma is marked by Reed-Sternberg cells, a specific type of abnormal lymphocyte. Symptoms in children may include:

• Painless swelling of lymph nodes in the neck, armpit, or groin
• Persistent fever
• Unexplained weight loss
• Night sweats
• Fatigue

Treatment for childhood Hodgkin’s lymphoma usually involves chemotherapy and radiation therapy. The treatment plan depends on the cancer’s stage and location, as well as the child’s age and health.

Non-Hodgkin’s Lymphoma in Children

Non-Hodgkin’s lymphoma is more common in children than Hodgkin’s lymphoma. It can occur in various parts of the body, including the lymph nodes, spleen, bone marrow, and other organs. Symptoms may include:

• Painless swelling of lymph nodes
• Abdominal pain or swelling
• Fever
• Unexplained weight loss
• Fatigue

Pediatric lymphoma treatment for non-Hodgkin’s lymphoma usually involves chemotherapy. In some cases, radiation therapy or stem cell transplantation may be necessary. The specific treatment plan depends on the type and stage of the lymphoma, as well as the child’s age and overall health.

The table below compares the two types of childhood lymphoma:

Advances in childhood lymphoma research have led to improved survival rates. Long-term follow-up care is essential to monitor for late effects of treatment and ensure the best outcomes for children with lymphoma.

Childhood Sarcomas

Childhood sarcomas are rare cancers found in kids and teens. They grow in bones, muscles, or connective tissues. These cancers make up about 15% of all cancers in young people. The main types are osteosarcoma, Ewing’s sarcoma, and rhabdomyosarcoma.

Osteosarcoma is the most common bone cancer in kids. It usually happens in the long bones of arms and legs. Kids might feel pain, swelling, and have trouble moving the affected area. Doctors use X-rays and MRI scans to find the cancer. A biopsy confirms it.

Treatment for osteosarcoma includes chemotherapy, surgery, and sometimes radiation. This helps remove the tumor and fight the cancer.

Ewing’s sarcoma is another bone cancer that can start in soft tissues. It often affects the pelvis, thigh, and upper arm. Symptoms are similar to osteosarcoma, like pain, swelling, and fever. Diagnostic procedures for Ewing’s sarcoma include imaging tests and biopsies.

Treatment for Ewing’s sarcoma combines chemotherapy, surgery, and radiation. This approach helps fight the cancer.

Rhabdomyosarcoma is a soft tissue cancer that grows in muscles. It often happens in the head, neck, or limbs. Symptoms include a painless lump, swelling, and trouble with bodily functions. Doctors use imaging tests and biopsies to diagnose it.

Treatment for rhabdomyosarcoma includes chemotherapy, surgery, and radiation. The treatment plan depends on the patient’s age, where the tumor is, and how advanced it is.

Research has improved how we diagnose and treat childhood sarcomas. But these cancers are hard to beat. Ongoing studies aim to find better treatments with fewer side effects for young patients. Early detection and treatment by pediatric oncology teams are key to better outcomes and quality of life for kids with these cancers.

Rare Childhood Cancers

Leukemia, brain tumors, and lymphoma are common in kids. But, there are rare cancers that affect fewer children. These cancers are hard to diagnose and treat.

Retinoblastoma

Retinoblastoma is a rare eye cancer in young kids, usually under 5. It grows in the retina. Symptoms include:

• A white pupil (leukocoria)
• Crossed eyes (strabismus)
• Vision problems

Treatment options are chemotherapy, radiation, laser therapy, or surgery. It depends on the tumor’s size and location.

Wilms’ Tumor

Wilms’ tumor, or nephroblastoma, is a rare kidney cancer in kids. It mostly affects children aged 3 to 4. Symptoms include:

• A swollen abdomen
• Abdominal pain
• Fever
• Blood in the urine

Surgery to remove the kidney is often the first step. Then, chemotherapy and radiation might follow.

Neuroblastoma

Neuroblastoma is a rare cancer from immature nerve cells. It mostly affects kids under 5. Symptoms vary by tumor location but may include:

Treatment often combines chemotherapy, surgery, radiation, and stem cell transplant.

Though rare, cancers like retinoblastoma, Wilms’ tumor, and neuroblastoma are tough. But, thanks to better diagnosis and treatment, kids’ chances of survival have improved. More research is needed to find better treatments and improve survival rates.

Diagnosis and Treatment of Childhood Cancer (Pediatric Cancer)

Diagnosing and treating childhood cancer needs a team effort. It combines new medical tech with the skills of many experts. Finding cancer early and accurately is key to better survival rates.

Advances in Pediatric Cancer Diagnosis

Recently, big steps have been taken in finding cancer in kids. New imaging like MRI and CT scans help doctors spot tumors better. Tests like molecular testing and genetic sequencing help find the exact cancer type. This means treatments can be more focused and effective.

Chemotherapy for Childhood Cancer

Chemotherapy is a big part of treating childhood cancer. It uses drugs to kill cancer cells all over the body. Doctors make a special plan for each child based on their cancer type and health.

Chemotherapy can make kids lose their hair and feel sick. But, there are ways to help them feel better and keep their quality of life good.

Radiation Therapy for Pediatric Cancer

Radiation therapy uses beams to kill cancer cells in a certain area. It’s often used with chemotherapy and surgery for cancers like brain tumors. New tech, like proton beam therapy, helps target cancer better and protect healthy tissue.

It might cause some side effects like skin problems and tiredness. But, these usually go away once treatment ends.

Surgery in Treating Childhood Cancer

Surgery is very important in treating childhood cancer. It aims to remove as much tumor as possible while keeping healthy tissue safe. New, smaller surgery methods help kids heal faster.

In some cases, surgery is used with other treatments for the best results. A team of experts works together to treat childhood cancer. Thanks to new research and treatments, kids with cancer have a better chance of recovery.

Supportive Care for Children with Cancer

Support for kids with cancer goes beyond just medicine. It covers their emotional, social, and practical needs. Pediatric cancer care teams focus on giving kids the help they need to deal with cancer’s challenges. This includes managing side effects, helping with emotional well-being, and supporting families.

Healthcare experts work with families to teach them about the cancer journey. They offer tips on nutrition, pain control, and managing side effects like tiredness or nausea. Counseling and support groups are also part of the psychosocial support to help families emotionally.

Surviving cancer long-term is a big part of pediatric care. As more kids beat cancer, they need ongoing support. Survivorship programs offer regular check-ups, health monitoring, and educational and social help. This way, healthcare teams aim to make life better for kids and their families during and after cancer.
